Definitions

  • the present invention relates to the selection of a destination for use in route calculation in a vehicle navigation system, to a method, a computer program product, and a data table in a memory for use in the system.
  • a particular arrangement to be described below, by way of example in illustration of the present invention includes means by which a user of a vehicle navigation system may conveniently select a city as a destination even where the streets of that city have not been digitized and included in the system's map database.
  • the user may specify a desired destination in a variety of ways. For example, when it is known, the user may specify the street address of the destination. Alternatively, the user may, for example, specify an intersection of two roads in the vicinity of the destination. Once the user selects one of these alternative methods for designating the destination, the user may be prompted to select a city from a displayed city list. In response to the selection of a city, the user may then be prompted to select the appropriate street or streets from a displayed list of streets corresponding to the selected city. Obviously, for either of these alternatives to be available, the streets of the city in which the destination is located must be represented by digitized data in the system's map database. However, because there are many small towns outside of major urban areas which have not yet been digitized, the map databases which may be used are not able to have much, if any, street data for such towns.
  • a flowchart 100 for use in illustrating a particular method for selecting a destination for route calculation using a street address is shown.
  • a city list 152 is presented at 104 which includes all of the cities for which digitized street data exist in a map database 154, i.e., digitized cities.
  • a street name list 156 is presented 108 which includes all of the streets in the map database 154 corresponding to the selected city.
  • the user is prompted to enter a street address 112. Once a valid street address has been entered 114, the navigation system employs the specified address as the destination for the route calculation 116.
  • Fig. 2 is a flowchart 200 for use in illustrating another method for selecting a destination for route calculation using an intersection.
  • a city list 152 is presented at 204 which includes all of the cities for which digitized street data exist in the map database 154, i.e., digitized cities.
  • a first street name list 156 is presented 208 which includes all of the streets in the map database 154 corresponding to the selected city.
  • a cross street name list 252 is presented 212 which includes all cross streets corresponding to the selected street name.
  • the user when a user indicates a desire to designate a specific street address or intersection, the user is typically presented with a list of cities. However, if the streets of the town in which the destination is located are not included in the system's map database, the town is not included in the city list. That is, the city list displays only cities and towns for which digitized street data are stored in the map database. Non-digitized cities are not represented in the city list.
  • some systems which allow the user to specify a point of interest POI such as, for example, an amusement park or a restaurant.
  • city centers or downtown areas are included as a POI category.
  • a list of cities and towns is displayed.
  • this city center list includes towns for which digitized street data are not available.
  • the centers or downtown areas of such towns are represented in the map database as a single location with reference to, for example, a highway which passes through the town and for which map data are available.
  • Fig. 3 is a flowchart 300 for use in illustrating a method for selecting a destination for route calculation using points of interest POI, for example, amusement parks, museums, restaurants, and downtown areas or city centers.
  • a list of POI categories 352 is displayed 304 which includes a number of categories of points of interest stored in map database 154.
  • a city center list 354 is displayed 310 which includes all of the cities in map database 154 regardless of whether database 154 has digitized street data for the listed cities. That is, both digitized and non-digitized cities are represented in city center list 354.
  • the city center is used as the destination for route calculation 318.
  • the appropriate POI list 356 corresponding to the selected category is displayed 314.
  • Individual POI lists 354 and 356 may either be generated during database compilation, or on the fly during system operation from a single large POI list which includes POls across all categories.
  • the selected POI is used as the destination for route calculation 318.
  • a vehicle navigation system will be described below, by way of example in illustration of the present invention, which allows a user easily to select a destination for the purpose of route calculation by designating the city in which the destination is located regardless of whether street data is available for the city.
  • This is accomplished in the particular example by displaying a more inclusive city list in response to the selection by the user of a destination selection option which relies on the availability of street data. That is, if a user indicates a desire to designate a destination using a street address, a city list is displayed which includes non-digitized cities, i.e., cities for which no street data are available in the system's map database.
  • the user may still select the city as the destination city without having to look for it elsewhere.
  • the user will not be able to specify a street address. Instead, the city center or downtown area of the selected city will be designated as the destination.
  • a method for selecting a destination in a vehicle navigation system A plurality of options will be described for designating the destination in the system's user interface.
  • a first option employs at least one street name to designate the destination.
  • a list of cities is provided for display in the user interface.
  • the list of cities includes a first plurality of cities for which no street names are available for display.
  • a first location associated with the first one of the first plurality of cities in the map database is selected as the destination.
  • sparsely digitized cities are also included in the list of cities. That is, the list includes cities for which only selected roads are digitized.
  • a street name list is provided which includes the street names for the digitized roads and an entry corresponding to a specific location in the selected city.
  • a specific embodiment of a vehicle navigation system 400 for use with the present invention is shown.
  • Sensors 412 and 414, a traffic data receiver 416, and a GPS receiver 418 are coupled to computing means 420 through G/PS/sensor interface 422.
  • a mileage sensor 412 includes an odometer
  • an angular velocity sensor 414 includes a gyroscope, or a differential odometer coupled to the wheels of a vehicle.
  • the traffic data receiver 416 may include any of a wide variety of RF receivers which are operable to receive real time traffic data transmitted in a variety of formats.
  • a global positioning system (GPS) data receiver 418 is provided for receiving signals from, for example, a satellite-based navigation system.
  • GPS global positioning system
  • Data from the GPS/sensor interface 422 is transmitted to a CPU 424, which performs the calibration, signal processing, dead-reckoning, vehicle positioning, and route calculation and guidance functions.
  • a database containing map information may be stored in a database medium 426, with software directing the operation of the computing means 420 stored in a main memory 428 for execution by the CPU 424.
  • the memory 428 may be any of a wide variety of non-volatile memory, for example, read-only memory (ROM), a reprogrammable non-volatile memory such as a flash memory or an SRAM, or any other type of memory such as a CD ROM, an optical disk, or one or more PCMCIA cards.
  • a system RAM 430 permits the reading and the writing of the information necessary to execute such software programs.
  • the database medium 426 may be a non-volatile memory, a hard disk drive, a CD-ROM, or an integrated circuit in which digitized map information has been stored.
  • An output controller 432 which may be a graphics controller, receives data processed by the CPU 424 and transmits the data to to display console 440 which includes an output communicator 434, usually a display screen.
  • the user may input data, such as a desired destination, through a user interface 436, typically a keyboard.
  • the map database stored in the database medium 426 preferably includes positional data, for example, latitude and longitude coordinates, to describe road intersections or nodes, road segments, landmarks and points of interest, and other geographical information.
  • the database may further include data representing characteristics of roads or places on the map, such as road and place names, road features such as dividers, one-way restrictions, surface, speed limit, shape, elevation, and other properties.
  • the map database includes cost values associated with individual nodes and road segments. These cost values correspond to the estimates of time intervals for traversing a respective node or segment. Node cost values take into consideration such information as, for example, whether the vehicle would encounter oncoming traffic, thus delaying a left turn manoeuvre.
  • Segment costs reflect road segment characteristics such as speed limit and segment length, both of which affect the travel time along the segment.
  • a hierarchy value which relates to the category or type of the road. For example, the highest level category of the hierarchy includes freeways and expressways. The lowest level includes residential streets and/or alleys.
  • the information stored in the map database medium 426 is employed with the data received from the interface 422 for route calculation and guidance. Examples of route calculation and guidance techniques for use with the present invention are described in the specification of commonly assigned, copending U.S. Patent Application No. 08/784,204 for ROUTE GENERATION IN A VEHICLE NAVIGATION SYSTEM filed on January 15, 1997, and corresponding European Patent Application No. 98300263.5 which was published under No. 854353 on July 22 1998 .
  • a flowchart 500 illustrating the selection of a destination for route calculation in one particular arrangement illustrative of the invention.
  • list refers to an organized collection of data such as, for example, an alphanumerically organized list on a display screen, or a corresponding data table in a database having data therein which corresponds to the alphanumeric entries.
  • an enhanced city list 552 is displayed 504 which includes all of the cities from the city list 152 and the city center list 354, i.e., both the digitized and non-digitized cities represented in the map database 154.
  • An enhanced city list 552 may be generated during the compilation of the database 154 or, alternatively, on the fly while the navigation system is operating by referring to city list 152 and the city center list 354.
  • the city center data are returned as the destination 510 which is then used for route calculation 512.
  • the selected city is a digitized city, i.e., the map database 154 contains digitized street data for the selected city, and the designation of the destination continues in a conventional manner, as described above with reference to Figs. 1 and 2 . That is, if the street address option were to be selected, the process would proceed from the step 108, and if the intersection option were to be selected, the process would proceed from step 208.
  • the user may still select the street address or the intersection option for designating the destination.
  • the user will not be able to enter a specific address, or select a particular intersection in the non-digitized city, but the user will at least be able to select the city center without having to "back out” of the selection process and select the city center as a point of interest. This is particularly important where, as in the case of use with a rental car, the user is not familiar with either the navigation system interface or the local geography.
  • the city center list 354 will also typically include sparsely digitized cities for which only selected roads are represented in the database.
  • the user is presented with an enhanced street list including the digitized streets corresponding to the selected city and also including a specific location in, for example, a downtown area.
  • the user is provided with a selection option even where a desired street name is not available.
  • an enhanced street name list 554 is presented 516 which includes an entry corresponding to, for example, the city center of the selected city. Where the city center is selected from the list 554,518, it is used as the destination for route calculation 512.
  • the designation of the destination continues in the conventional manner as described above with reference to Figs. 1 and 2 . That is, if the street address option were to be selected the process would proceed from step 108, and if the intersection option were to be selected the process would proceed from step 208. In addition, were a street name to be selected from the enhanced street name list 554 at step 518, the designation of the destination would also continue in the conventional manner, as described above with reference to Figs. 1 and 2 . That is, if the street address option were to be selected the process would proceed from step 112, and if the intersection option were to be selected the process would proceed from step 212.
  • Fig. 6 there is a flowchart 600 for use in illustrating the generation of an enhanced city list according to various specific arrangements.
  • generation of the enhanced city list by the process illustrated in Fig. 6 occurs during the compilation of the system's map database. That is, during the initial system configuration, a permanent enhanced city list is generated for use in place of the city list during normal system operation.
  • the process of Fig. 6 beginning at 604 occurs "on the fly", i.e., while the vehicle navigation system is operating. That is, an enhanced city list is generated from the city list and city center POI data, for example, after system boot-up, or in response to a user's request to view the city list.
  • a plurality of the lists employed by the various system processes during normal system operation are generated 602 from the raw data in the database provided by any of a variety of vendors.
  • Such lists include, for example, lists of states, counties, cities, roads, points of interest (POls), etc.
  • the POI list generated during this compilation may include a single large list of all points of interest (e.g., amusement parks, restaurants, city centers, etc.) in the database.
  • individual POI lists may be generated during database compilation for each POI category. It will be understood that, in any case, the POI data may be organized in a variety of ways without departing from the scope of the protection sought, which is determined by the appended claims.
  • the process illustrated at 600 goes to the first city center in the appropriate POI list 604.
  • This may be either a POI list including all types of POls or a POI list of city centers, depending upon the nature of the lists generated in 602. If the first city center in the POI list is not represented in the city list 606, the city center is added to the city list 608 thereby altering the city list and beginning the generation of an enhanced city list. If the city center most recently added to the enhanced list is not the last one in the POI list 610, the process advances to the next city center in the POI list 612 and determines whether it is represented in the city list 606 .
  • the process again determines whether the city center is the last one in the POI list 610 and, if not, moves to the next city center entry in the POI list 612. If, however, the last city center in the POI list has been reached, the process ends and the enhanced city list is complete.
